I see people still trying to patch files to get root.

If you flash the TWRP posted by @Talich52, with reboot unchecked you can install Magisk from TWRP.

Tested on T295XXU3BUC3 ROM (Android 10)

PREREQUISITES:

Bootloader unlocked - search forums.xda-developers for instructions how to do this.

OEM unlock on. In Settings/developer options, OEM Unlock slider should be to the right.

INSTRUCTIONS:

1. If prerequisites met: install Android 9 bootloader through ODIN (See attachement: Unzip BL*.zip FIRST)
If on Android 9, go to step 3.

2. Reboot to system

3. Go into download mode.

4. Open ODIN and in the AP slot put TWRP (see attachment below) (Unzip FIRST)

5. Uncheck auto reboot

6. Flash TWRP

7. Press vol dn + pwr keys.

8: When screen goes blank, press vol up + pwr keys.

9. Keep holding down both keys after reboot.

10. Tablet will reboot again.

11. When Samsung logo appears stop pressing pwr key.

12. When bootloader msg appears, release vol up key, quickly press & release pwr key, and quickly press & hold vol up key until in TWRP.

13. Install Fix_vendor_9.0.zip or Fix_vendor_10.0.zip. (Based on installed OS)
See attached files.

14. Clear dalvik/cache if prompted

15. You will then format (NOT WIPE) data. Answer yes to the format prompt

16. Clear dalvik and cache.

17. Reboot back into recovery.

18. Install magisk - see attached

19. Reboot into system. System may reboot again - that's okay

20. Enjoy!!


WETAmod: (For Android 10 ONLY)

I have attached a zip file which will add 3Minit Battery, alternate battery options, 3Minit Clock & Network Meter options to the status bar. There are other options inn the WETAmod package. I have tested all the options and they should all work.. Also includes reboot, download, recovery, shutdown tiles for the taskbar dropdown menu (check buttons). On the audio options page, there are instructions for installing Viper4Android - Please READ CAREFULLY.

The original WETAmod package was developed by @Mentalmuso. He kindly allowed me to post my modified version for the SM-T295 on this forum.

IMPORTANT:
The WETAmod*.zip file HAS TO BE INSTALLED in Magisk Manager.

1. At the bottom of Magisk Manager, you will what looks like a puzzle piece on the right side. Press it. (attachment MM-1.png)
2. At the top of the Modules page, press 'Install from Storage'
3. Find & select the WETAmod_T295_1.zip on your tablet's storage.
4. Installation info will be displayed during install.
5. Reboot
6. In the Apps Drawer, launch the WETAmod app. You can browse the options from the menu

NOTE:
If the 3MinitBatterySettings is not downloading the battery styles, reinstall the 3MinitBatterySettings.apk. You can extract it from the WETAmod zip file.

Hi! Great work! Got root and twrp on buc3.

I'm really interested with custom roms, since I got twrp I tried lineageos 17.1 gsi but it goes into bootloop. I tried following various instructions from everywhere in the internet but to no avail.

Recently, I saw ur conversation with secretwolf and that he claimed he was able to flash gsi roms. Since there is not much difference between 290 and 295, I think it's not too far fetched to have a custom rom flashed on the 295.

Do you have any ideas on how to go about it? Thanks!

I have been staying with Samsung roms for now. I may try LineageOS in the future. But, to answer your question, maybe try and clear the data partition

This looks amazing I have a tablet on order and wish to do this.
May I please ask, once magisk is installed is that rooted done, or do I need to activate/configure magisk to root or install a module into it please (only used supersu before so unsure of magisk).

Thank you
Alex

    EFTSU file doesn't work too, same "security check fail: boot.img" as magisk patched files did.

    The T295XXU4BUD5, file name "SM-T295_T295XXU4BUD5_10_567dd.9EFT"
    Unless they extracted the correct key signature from the original files, modified TWRP, kernel with it, I do not see how they can get root on U4BUD4/5

    Also, most of the Samsung cpus on this site are Exynos
